A student is taking a multiple-choice exam in which each question has two choices. Assuming that she has no knowledge of the correct answers to any of the

questions, she has decided on a strategy in which she will place two balls (marked A and B) into a box. She randomly selects one ball for each question and replaces
the ball in the box. The marking on the ball will determine her answer to the question. There are five multiple-choice questions on the exam.
